How deep is each part of the Mozambique Channel?
The bar splits the Mozambique Channel's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 11.5%
- 200 to 1,000 m: 6.3%
- 1,000 to 4,000 m: 79.9%
- 4,000 to 6,000 m: 2.3%
- below 6,000 m: 0%

The Mozambique Channel if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Mozambique Channel's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 19,702 km² | 1.4% |
| 20 m | 56,609 km² | 4.1% |
| 50 m | 126,808 km² | 9.3% |
| 80 m | 140,503 km² | 10.3% |
| 120 m | 148,276 km² | 10.8% |
| 200 m | 157,616 km² | 11.5% |
| 500 m | 191,383 km² | 14% |
| 1,000 m | 244,016 km² | 17.8% |
| 2,000 m | 431,902 km² | 31.5% |
| 3,000 m | 861,967 km² | 62.9% |
| 4,000 m | 1.3 million km² | 97.7% |
| 6,000 m | 1.4 million km² | 100% |
A simple bathtub model: it lowers the sea everywhere by the same amount and does not simulate how water would really drain.

Frequently asked questions
How deep is the Mozambique Channel?
On average about 2,310 m in the GEBCO grid (the middle value is 2,623 m). The deepest cell inside its outline is 4,701 m, at 26.10° S, 38.54° E.
How big is the Mozambique Channel?
About 1.4 million km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Mozambique Channel would be land if sea level dropped?
With the sea 10 m lower, about 19,702 km² (1.4%) of its water would be land. At 6,000 m lower, 100% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
